description Concatenating condition refers to combining multiple conditions using logical operators to create more complex and sophisticated conditionals.

Concatenate

Furthermore, you can concatenate different conditions with "or" or “and” statements, to test whether either statement is true, or both are true, respectively.

In JavaScript “or” is written as || and “and” is written as &&.

Say you want to test if the value of x is between 10 and 20. You could do that with a condition stating:

if (x > 10 && x < 20) {
    ...
}

If you want to make sure that country is either “England” or “Germany” you use:

if (country === "England" || country === "Germany") {
    ...
}

Note: Just like operations on numbers, conditions can be grouped using parenthesis, ex: if ( (name === "John" || name === "Jennifer") && country === "France").
